UNITE STATES ATENT IQEQ PLOW.

SPECIFICATION forming part of Letters Patent No. 254,734, dated March 7, 1882.

(No model.)

To all whom it may concern Be it known that I, JAMES VANDEGRIFT, of Princeton, in the county of Bureau and State of Illinois, have invented a new and useful Improvement in Flows; and I do hereby declare that the following is a full and exact description of the same, reference being bad to the accompanying drawings, and to the letters of reference mark-ed thereon.

In that class of plows heretofore provided with one and two bearing-wheels in the bottom thereof, between the landside and the mold-board, it has been proved upon practical test that the tread of such wheel or wheels is uneven, as is also the balance of the plow, necessarily requiring as much labor and skill on the part of the plowman to conduct the plow as is requisite with the use of the common or ordinary plow. As the means sought is essentially to lessen the labor of the plowman and diminish the draft, I have provided will obviate any excess of labor or draft, and,

further, so effectively accomplish the means sought as to make the plowman merely a guide to the plow, devoid of all other incident work, all as more fully hereinafter described and claimed.

For the better understanding of my invention, and to enable those skilled in the art to which it relates to know how to construct and use the same, I will proceed to describe it, having reference to the accompanying drawings,

in which---- a metal strip, a, whose other end extends across therefrom to a point almost directly opposite on the mold-board, to which and the prowshare it is rigidly secured. This strip a thus forms a substantial brace for the connection of the landside and mold-board, and further serves as a suitable and convenient means for the attachment and support of the arm I), upon which are mounted the bearing-wheels c d a, respectively. This arm I), just alluded to, is secured near its center to the brace a, as shown, and runs parallel with the line of the landside. Upon the forward end of this arm I), in the recess formed by the junction pf the landside and mold-board, is mounted the wheel 0, by means of a shaft connecting said end with the landside.

.The wheel (I is mounted in a like manner next to the landside upon the rear end of the arm, and consequently travels directly in the track of the forward wheel. Although these two wheels come in close proximity to the landside, they must not be so close as to clog or be V -share such a distance as may be desired.

Having thus described my invention and set forth its accomplishments, what I claim, and desire to secure by Letters Patent, is-

In a plow, the combination of the bearingframe a b f, substantially as described, with Y the wheels 0, d, and c, mounted and arranged substantially as described, and for the purpose set forth.

This specification signed and witnessed this 19th day of December, 1881.
